<date of first letter> I sent you a letter regarding my dissatisfaction with the <vehicle name, year, etc.> I purchased from your dealership <date of purchase>. The problems I have been experiencing with <problems with car> have continued, and I have yet to hear from you or any <dealership name> representative.
Please contact me immediately upon receiving this letter. I am thoroughly unhappy with this vehicle, which in my opinion is defective and should be replaced by <dealership name> and <car manufacturer> at no cost to me and without delay.
I will expect to hear from you within the next week so that we may resolve this problem to the satisfaction of all parties. Thank you.
